Open Source Cryptography Software

Cryptomator is a free and open source project that offers multi-platform, transparent client side encryption of your files in the cloud. It works with just about any cloud storage service; is totally transparent so you can work with your files how you normally would; and secure with a 256-bit key length AES encryption. It’s also simple and easy to use with no need for different accounts, key management, cloud access grants or cipher configurations.

AirSnort is a wireless LAN (WLAN) tool which cracks encryption keys on 802.11b WEP networks. AirSnort operates by passively monitoring transmissions, computing the encryption key when enough packets have been gathered.

axTLS is a TLSv1 SSL library designed specifically for embedded devices, with a highly configurable interface for small memory footprints.

Simplebackup is a cross-platform backup program. It reads a configuration file then builds a compress backup set, finally places the compressed files into another location (a directory, a remote http,ftp,sftp server or even one or more email accounts).

WASTE is a mesh-based workgroup tool that allows for encrypted, private communication between distant parties on the internet, independant of local network organization.

HPN-SSH is a series of performance patches for OpenSSH. By addressing network limitations and CPU limitations significant throughput performance can be realized. Gains of close to two orders of magnitude are possible on long fat network paths. The official git repo is now available at http://github.com/rapier1/openssh-portable. The Sourceforge repository should not be seen as the canonical repository for HPN-SSH. We will update it as we can but users should look to github to generate patches We also support Ubuntu packages. Add them to your package manager with `sudo add-apt-repository ppa:rapier1/hpnssh` Fedora RPMs can be added with, `sudo dnf copr enable rapier1/hpnssh`

ReHash is an easy-to-use console-based hash calculation tool written in C++. It supports many algorithms and output formats and it can be fully configured using some of the many command-line arguments which can be passed to the tool.

QPass is easy to use, open source password manager application with built-in password generator. You can store in it's database such data as passwords and logins which will be encrypted using AES-256 with PBKDF2(number of iterations set by user). Each entry can include additional information about entry such as name, url adress and description.

silvertunnel.org is a project that provides an end-user browser, a Java library and additional Java security tools to easily access anonymity networks such as the Tor (torproject.org) network. Secure and easy to use. Tor4Java and Tor Browser. Attention: see project status on page https://sourceforge.net/p/silvertunnel/discussion/962278/thread/83dc2d02/#

ECTP - Encrypted Compressed Transfer Protocol This protocol is similar to HTTP but with commands and features like FTP. The main features are security and compression abilities and the consequent use of one perisistant connection.

siggen is a cool email signature generator for encrypted ansi c (confused), brainf*ck, ... signatures. Use it in combination with vi(m), emacs, mutt, pine, or what ever. (tested on Solaris, Linux and Windoze). Optimized only for geeks :-)

Cryptomak contains cipher and tools for encryption utility written in php such as substitution, vigenere, affine, transposition and index of coincidence. It is powered by Phrame platform which implements MVC design and Smarty template engine.
